Overall I like this change. I'm wondering if we should add something like "CSR" either before or after the CSR link to make it clearer what the issue link is. I would suggest a bold CSR within normal parentheses after the title. This matches the formatting of the reviewer attributions further down in the body.

bots/pr/src/main/java/org/openjdk/skara/bots/pr/CheckRun.java line 137:

I don't think we should throw an exception here. If we do, then a bad state in JBS will completely prevent the PullRequestBot from updating the status of the affected PR. I would prefer logging a warning and returning Optional.empty().
